Sam Zweerink :
Has anyone done the quick training? Any tips on that.
Quick Training costs you 10 gold balls per "session" and gives you the same amount of training as what the intensive training session gives you, but you do not lose any energy or take time to recover for the next training session. You can do this as many times as you like or do it as a big training session with say 100 gold balls (so 10 x intensive training) without energy loss.
This is basically like a booster training session that you buy.
